Hello, thank you for posting,

Your balance resembles the S350-28 channel balance. Please review the overall style to confirm. As for the stamps. The 27 3 translates to a 2730 stamp option that can support a 13 to 19 pound window sash. I recommend weighing the window sash to confirm that the window sash falls into this range.

We do not have a stamp that translates from the 27 8 stamp. To further review, are you able to provide the weight of the window sash? The sash will need to be removed and weighed on a bathroom scale. Thank you!
